EXAMPLE 6.3 Bungee Jumper A bungee jumper locates a suitable bridge that is 75.0 m above the river below, as shown in Figure 6.14. The jumper has a mass of m-80.0 kg and a height of Ljumper 1.85 m, we can think of a bungee cord as a spring. The spring constant of the bungee cord is k-50.0 N/m. Assume that the mass of the bungee cord is negligible compared with the jumper's mass Lo PROBLENM The jumper wants to...

Consider a bungee jumper dropping vertically in freefall from a bridge 80 m above the ground. After three seconds, the elastic cord connecting the jumper to the bridge starts to stretch, which changes the jumper's acceleration to 15 m/s2 upwards. a) Sketch (without doing any math) the position vs time, velocity vs. time, and acceleration vs. time graphs for the bungee jumper from the moment they start to fall to the moment they reach the closest to the ground. b)...

7. A bungee jumper with mass m 50 kg leaps fron a bridge. The jumper is attached to the bridge by an elastic cord with axial stiffness k = 0.10 kN m-1. The cord unravels to its ful unstretched length 3.0s after the jumper has left the bridge. Starting from when the jumper leaves the bridge, determine the earliest time at which the elastic cord reaches its maximum extension. Neglect air resistance.[15

A 68 kg bungee jumper is standing on a platform 46 m above the ground. The jumper falls from rest and it is assumed that the bungee cord, which is attached to the bungee jumper at one end and the platform at the other, has no effect for the first 9 m of the fall, i.e. the natural length of the cord is 9 m. When the bungee jumper is more than 9 m away from the platform the cord...

A 59,3 kg bungee jumper jumps off a bridge and undergoes simple harmonic motion. If the period of oscillation is 20,5 s, what is the spring constant of the bungee cord, assuming it has negligible mass compared to that of the jumper? Answer in two decimal places.

A 65.2-kg bungee jumper is standing on a tall platform (h_0 = 46.2 m), as indicated in the figure. The bungee cord has a natural length of L_0 = 8.40 m and, when stretched, behaves like an ideal spring with a spring constant of k = 48.3 N/m. The jumper falls from rest, and it is assumed that the only forces acting on him are his weight and, for the latter part of the descent, the elastic force of the...

Problem 3. A bungee jumper of mass 72.0 kg jumps from a cliff. After reaching his lowest point, he oscil- lates up and down. He is observed to reach his lowest point 9 times more in 45.0 s. Assume the bungee cord obeys Hooke's law. (a) What is the period of his motion? (b) What is the force constant of the bungee cord? (c) After oscillating for a while, the jumper finally comes to rest 30.0 m below his starting...

When bungee jumping from a high bridge over Victoria Falls, an operator first attaches an elastic rope to the jumper. The jumper then jumps off the bridge, falling freely until they reach the unstretched length of the rope Then, the rope begins to stretch and slows the jumper to a stop. The rope pulls the jumper back up, and they oscillate up and down for a while until the operator pulls the jumper back up to the bridge. The rope...

An adventurous bungee jumper is in the process of dropping into
a gorge from a bridge. He has thought ahead to wear a helment and
other safety gear. At this moment in time, he has reached the
equilibrium position of his bungee , is L meters below the bridge
and h meters above the river below. He has a mass M.
a) What is his total potential energy as a function of his
distance x from equilibrium?
b) What is...
